Copeland 918-0009-02 Crankcase Heater

Efficiently manage compressor temperatures with the Copeland 918-0009-02, a heavy-duty bolt-on crankcase heater engineered for 480V industrial refrigeration and HVACR systems. Delivering a constant 65W output, this heater is an essential component for preventing refrigerant migration to the compressor shell during off-cycles. By maintaining the oil at an optimal viscosity, it helps avoid liquid slugging and ensures immediate lubrication at startup, specifically in Copeland Copelametic and Discus processors where maintaining oil temp is critical in low ambient conditions.

The Copeland 918-0009-02 features a 10-inch diameter design, allowing for a secure, high-contact fit around the crankcase for maximum thermal transfer. Built for field reliability, it includes 31-inch leads and a 23-inch conduit length to facilitate clean routing in tight mechanical cabinets. As a 480V 65W crankcase heater, it provides stable heat without the risk of carbonizing the oil, meeting the strict requirements for 3R, E, L, M, and N compressor models (excluding deep sump variants).

• Prevents Refrigerant Migration: Actively keeps the crankcase warmer than the evaporator to stop vapor from condensing in the oil.
• Optimized Cold Starts: Maintains oil fluidity in rooftop or outdoor units to ensure consistent oil pressure upon engagement.
• Direct Bolt-On Compatibility: Specifically designed for Copelametic and Discus compressor bodies for a precise, secure installation.
• Industrial Grade Protection: Robust construction and 480V rating ensure performance in demanding commercial power environments.

Is the 918-0009-02 compatible with deep sump compressors?
No, this specific bolt-on model is designed for standard sumps. Deep sump models typically require immersion-style heaters for proper oil penetration.

When should the crankcase heater be energized?
The heater must remain energized during all off-cycles. It is recommended to power the heater for at least 12 hours before the initial compressor startup to ensure all refrigerant is boiled out of the oil.

Can I use this on a 240V system?
No, this unit is rated strictly for 480V. Operating at a lower voltage will significantly reduce wattage output and cause inadequate heating, potentially leading to compressor failure.
